Oracle Rac opatch auto的時候爲何不打到Rac database home上

先交代環境：

操做系統：AIX 7.1

Oracle版本：Oracle Rac 11.2.0.3

以前打了11.2.0.3.9的補丁集，Rac裝上還沒正式用，因此就乾脆再打到最新的11.2.0.3.11補丁集。

今日在前段時間新裝的兩套Rac打最新的psu，一樣使用opatch auto的方式來打psu，可是其中一套Rac是連同Rac和Grid一塊兒patch，而另外一套是隻patch Grid的補丁集。很鬱悶，兩套rac的crsconfig_params是基本同樣的，兩套Rac的相關配置都是我一手安裝配置的，爲何會有如此多誤差？

以下是Rac和Grid一同patch的那套Rac：

root@ODB01:/install/psu>    

經過查看Mos文檔：（Doc ID 1479651.1）得知，HDB中是有數據庫存在的（即經過dbca等形式建立數據庫的），而ODB上並無數據庫DB的存在。

ps：這時忽然想起來，前段時間確實在HDB上創建過數據庫，並作了一些數據遷移作測試。。。（愚鈍啊） 

opatch的時候oracle在發現沒有數據庫database註冊到OCR中，所以只是patch了Grid。

以下：經過Mos提供的命令發現HDB上CRS中確實有ora.hdb.db的存在：

grid@HDB01:/home/grid>crsctl stat res -p -w "TYPE = ora.database.type"|egrep '^NAME|^ORACLE_HOME' 

NAME=ora.hdb.db

ORACLE_HOME=/oraapp/oracle/product/11.2.0/dbhome_1

ORACLE_HOME_OLD=

NAME=ora.hdb.db

ORACLE_HOME=/oraapp/oracle/product/11.2.0/dbhome_1

ORACLE_HOME_OLD=

grid@HDB01:/home/grid>

而在ODB上，次命令下去無任何輸出，查看一下/etc/oratab文件，確實未發現除ASM以外的其餘數據庫：

grid@ODB01:/home/grid>crsctl stat res -p -w "TYPE = ora.database.type"|egrep '^NAME|^ORACLE_HOME'

grid@SRMBODB01:/home/grid>

能夠經過如下命令來另外給Rac patch 補丁：

As root user, execute the following command:

opatch auto <UNZIPPED_PATCH_LOCATION> -oh <DATABASE_HOME> -ocmrf <ocm response file>
